A solution of acetic acid is prepared in water by adding 11.1 g of sodium acetate to a volumetric flask and bringing the volume to 1.0 L with water. The final pH is measured to be 5.25. What are the concentrations of acetate and acetic acid in solution? (Assume that the temperature of the solution is 25 degrees Celsius)
NaHCO3 balance g NaHCO3 s ⇒16.4 = 11.1+ ms ⇒ms = 5.3 b g
% crystallization = 5.3 g crystallized × 100% = 32 3%
16.4 g fed
Well, I can't help you with this question....but, you know what the pH of Mg(OH)2 is not 7.0. However, the final pH is measured to be 5.25.
